Maintenance and Repair 

Phone Cases 
Keeping your phone protected from damage should be pretty important to you. The phone case that comes along with your phone can effectively mitigate your concerns. realme original phone case is made of TPU material, which is lightweight and soft, and helps keep the original 'feel' of the phone, since the case is a tight-fitting overlay. It does a good job of protecting against drops and shock damage on the corners and rear of your phone, and can also reduce the damage caused by extreme temperatures, liquid, and dust invasion, etc.

Screen Protector
realme provides you with an original HD clear screen protector made of PET material, which is a thin piece of electro-conductive film that self-adheres to your screen. It protects your screen from cracking, and also offers resistance to scratches, fingerprints , and abrasions. Besides, the realme screen protector ensures high definition and sensitivity of the screen, which will not affect the screen display quality.

Maximize battery life and lifespan.

• Note: Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced. It is normal for the battery to lose its capacity over time, but you can do the following to maximize its life and lifespan.
• Use realme original accessories. Charge the phone with the realme original power adapter and USB cable. Charging with third-party charger accessories might impact battery lifespan or even cause security incidents.
• Use at a suitable temperature. realme smartphone battery is designed to have a good performance in a wide range of ambient temperatures, with 16° C to 25° C as the ideal comfort zone. When the temperature is higher than 45°C, battery capacity will be irreversibly damaged, and the phone might even short-circuit and burn.
• Do not use when charging. Programs such as long-time calls, games, or online videos will make the phone get warm quickly.
• Do not fully discharge your phone's battery. Charge your phone when your battery level goes down to 10%. If the phone's battery is fully discharged, the battery could fall into a deep discharge state, which will cause it to be slightly damaged.
• Store the phone long-term. If you plan to store the phone for a long time, charge it to 60% or above every month.
• External environment. Avoid exposing your phone battery to a humid environment or sun exposure.
• Keep a good using habit. Using features such as Bluetooth, Wi-Fi, and GPS or keeping them active in the background may drain the battery significantly. Turn them off when not in use to save the battery. Dimming your screen and reducing the screen timeout setting can also preserve the battery life.
• Do not charge with a portable power bank frequently. If a power bank supplies current that is above your phone battery's capacity, then it will cause damage to your battery gradually. Make sure the power bank you buy is of good quality, and has power ratings which are suitable for your phone, basically match the current to the wall charger you use.

Keep Clean

Your mobile phone could be a hotspot for bacteria, so cleaning your phone is of great importance. Follow these steps:

1. To clean your phone, unplug all cables and turn it off first.
2. Dip the included cleaning cloth or a soft, slightly damp, lint-free cloth in distilled water or low-concentration alcohol, and shake or squeeze to remove any excess liquid.
3. Slightly wipe across your phone. Avoid getting moisture in openings.
4. Gently wipe the screen with the dry part of the microfiber cloth, but don't try to pick up all the excess water if it means pressing hard.
   Do not attempt to dry your phone with an external heat source, such as a hair dryer. If impurities cannot be cleaned up, contact the realme Service Center for professional assistance.

Keep dry and solve water damage

Do not use your phone in the rain, or near washbasins or other wet locations. Take care not to spill any food or liquid on your phone. In case your phone gets wet, follow these emergency measures:

1. Take your phone out of the liquid immediately, unplug all cables, and turn off your phone.
2. If your phone has a removable battery, remove it.
3. Use a tissue or soft cloth to thoroughly absorb water stains or liquids on the surface of your phone, and gently shake the phone in the realmesite direction of liquid inflow.
4. Let your phone dry thoroughly before turning it on again. Avoid drying your phone with an external heat source, such as a hot air hair dryer.
   If your phone has a serious water damage, take your phone, warranty card, and proof of purchase to a nearby realme Customer Center for repairs at once.

Use connectors, ports, and buttons.
Never force a connector into a port,t for that might cause damage, which is not covered by warranty service. Check for obstructions on the port. If the connector and port don't join with reasonable ease, they probably don't match. Make sure that the connector matches the port and that you have positioned the connector correctly in relation to the port.

Other information
Mobile phones are perishable items;s, use them with care. The following instructions might help to protect your phone:

1. Do not drop your phone or let it receive a substantial impact.
2. Do not place your phone in a microwave oven or other high-voltage equipment; otherwise, it might cause damage, fire , or explosion.

6. Dirty sockets might cause poor contact or electrical leakage. Regularly clean the power socket.
